ISRAEL K. DIXON, (3F JOHNSTOWN, PENNSYLVANIA.

SWITCH Application filed. January To all whom it may concern:

Be it known that T, ISRAEL K. DIXON, a citizen of the United States, and resident of Johnstown, in the county of Oambria and State of Pennsylvania, have invented certain new and useful Improvements in Switch Tongues, of which the following is a specification.

This invention relates to switches and more particularly to tongue switches and has for one of its objects the provision of a novel means for holding the tongue down against the bed of the switch, which will permit ready removal.

Another object isto provide a switch of this character with a renewable flange bearing plate bedded on the switch body and adapted to cause the Wheels passing through the switch to ride on their flanges over the heel of the tongue. I

A further object is toprovide a novel adjustable mounting for the flange bearing plate, which will permit the adjustment of the plate to take up wear of the tongue and also compensate for manufacturing faults.

A still further object is to provide a switch having the novel construction, design, and combination of parts hereinafter described and illustrated in the accompanying drawings.

lln the drawings, Figure 1 is a partial plan of a switch embodying my invention.

Figure 2 is a side elevation.

Figures 3, i and 5 are transverse sectional elevations on the lines TIT-1H, Il -Ii and V-V, respectively.

Referring more particularly to the drawings, the numeral 2 designates the switch body which is provided with longitudinal groove 3, in which is mounted the usual tongue 4 having a circular heel 5.

The body 2 is cut away adjacent the outside of the heel of the tongue so as to expose the side face of the heel.

The heel 5 is cut away adjacent its exposed edge or side face to form a depression 6 and peripheral upstanding flange 7.

A hearing or wear plate 8 is mounted on the cut away portion of the body 2 and com prises an elongated member of sufficient width to overlie and substantially hill the depression 6 in the heel 5, thereby extending over a portion of the joint between the heel and the switch body. The lower face of the plate 8 is provided with a groove 9 adapted to receive the flange 7 on the heel 5, and the TDNGUE.

5, 1924;. Serial No. 684 641.

upper face of the plate is provided with a flange bearing groove 10 adapted to receive the flanges of wheels passing through the switch.

The lower wall or floor 11 of the groove 10 is elevated sufliciently to cause the flanges of wheels passing through the switch to ride thereon and thus raise the tread of the wheels off the tongue at the heel, thereby preventing any shock to the tongue heel and preventing the hammering thereof.

The plate 8 is removably and adjustably secured to the body 2 by bolts 12,13 and 14-. The bolt 12 extends transversely through the switch body and through the plate 8 and serves to take up the side thrust on the plate and also to adjust the plate transversely. The bolts 13 and 14 serve to hold the plate down tight against the heel 5 and body 2. The adjustable mounting of the plate permits it to be adjusted toward or against the heel 5 to take up wearand compensate for manufacturing faults. It will also be noted that the plate 8, as said before, effectively prevents the wheels passing through the switch coming in contact with the heel 5 or the joint between the heel 5 and the body 2, thereby preventing the hammering and wear thereof.

The plate 8, being removable, may readily be renewed and the life of the switch materially lengthened. Also the switch tongue may readily be removed by removing the plate 8, thereby eliminating the necessity of digging up the paving surrounding the switch and other laborious operations necessary to remove the tongues from switches commonly used.

While I have shown and described only one preferred form of my invention it will be understood that I do not wish to be limited thereto, since many modifications in design, construction and combination of parts may be made without departing from the scope of my invention as defined in the appended claims.

I claim:

1. A switch structure comprising the combination of a switch body, a tongue having a circular heel, and a flange bearing member extending over a portion of the joint between said heel and said body, so as to protect the heel and prevent the pounding down of said heel portion.

2. A switch structure comprising the combination of a switch body, a tongue having a circular heel, and a flange bearing member extending over a portion of the joint between said heel and said body, said flange bearing member being provided with a flange bearing groove, the floor of which is raised sufficiently to cause a flanged wheel passing through said switch to ride on the flange when passing over the heel of said tongue.

3. A switch structure,.comprising the combination of a switch body, a tongue having a circular heel, and a renewable flange bearing plate extending over a portion of the joint between said heel and said body.

4:. A switch structure, comprising the com bination of a switch body, a tongue having a circular heel, and a renewable flange bearing plate removably bolted to said body portion and extending over a portion of the joint between said heel and said body.

5. A switch structure, comprising the combination of a switch body, a tongue having a circular heel, and a renewable flange hearing plate removably bolted to said body portion and extending over a portion of the joint between said heel and said body, said plate being adjustable relative to said body portion to take up wear and compensate for manufacturing faults.

6. A switch structure, comprising the combination of a switch body, a tongue having a circular heel, and a renewable flange bearing plate, removably bolted to said body portion and extending over a portion of the joint between said heel and said body, said plate being adapted to bear against the top and outer side wall of said tongue, and being adjustable relative to said tongue and said body to take up wear and compensate for manufacturign faults.

, 7. A switch structure, comprising the com bination of a switch body, a tongue having a circular heel mounted in said body for pivotal movement, a renewable flange bearing plate extending over at least a portion of the joint between said heel and said body, and means for removably securing said plate in position on said body.

8. A switch structure, comprising the combination of a switch body, a tongue having a circular heel mounted in said body for pivotal movement, a renewable flange bearing plate extending over at least a portion of the joint between said heel and said body, and means for removably and ad justably securing said plate in position on said body. 7

9. A switch structure, comprising the combination of a switch body, a tongue having a circular heel mounted in said body for pivotal movement, a renewable flange bearing plate extending over at least a portion of the joint between said heel and said body, said plate being provided with a flange bearing groove, the floor of which is raised sufficiently to cause a flanged wheel passing through said switch to ride on the flange when passing over the heel of said tongue.

10. A switch structure, comprising the combination of a switch body, a tongue having a circular heel mounted in said body for pivotal movement, a renewable flange bearing plate extending over at least a portion of the joint between said heel and said body, said plate being removably bolted to the body portion of said switch.

11. A switch structure, comprising the combination of a switch body, a tongue having a circular heel mounted in said body for pivotal movement, a renewable flange bearing plate extending over at least a portion of the joint between said heel and said body, said plate being removably bolted to the body portion of said switch and adjustable relative to said switch body to take up wear of said heel and to compensate for manufacturing faults, said plate being provided in its upper face with a flange bearing groove, the floor of which is raised sufficiently to cause a flanged car wheel passing through said switch to ride on the flange when passing over the heel of said tongue.

In testimony whereof, I have hereunto set my hand.

ISRAEL K. DIXON.
